Châteauguay has 50,815 residents as of the 2021 census and is part of the Roussillon regional county municipality. Crossed by the rivière Châteauguay and bordered by lac Saint-Louis, the city borders the Mohawk territory of Kahnawake to the northeast. Île Saint-Bernard, where Héritage Saint-Bernard manages the refuge faunique Marguerite-D’Youville wildlife refuge, is one of its richest natural areas. Water and woods, right in the middle of the city, shape its pests.
Water, woods and major roads
Along the Châteauguay River and Lac Saint-Louis, many properties are wooded, with large trees and moisture (terrains boisés). Farther from the water, newer neighbourhoods stretch toward autoroute 30, which links Vaudreuil-Dorion to Sorel-Tracy, and route 138. Boulevard d’Anjou and boulevard Saint-Jean-Baptiste carry most of the commercial activity.
The two landscapes pose different problems: wooded and waterfront lots draw carpenter ants and wildlife, while neighbourhoods next to open land mostly see mice arrive in the fall.
The most common pests in Châteauguay
Carpenter ants. Dead wood, stumps, moisture and mature trees on wooded lots: the main nest of carpenter ants is often outdoors, linked to satellite nests in the house.
Mice. In the fall, mice look for shelter in homes, especially in neighbourhoods bordering open land. Sealing entry points remains the basis of treatment.
Wasps. Wooded lots offer plenty of natural nest sites, on top of soffits and decks. A nest near a door or a play structure justifies acting fast: see wasps and hornets.
Asian lady beetles. Houses next to woods and open land, with a sunny wall, attract Asian lady beetles in the fall.
Ticks. Not a residential extermination problem in the usual sense, but a real issue in the wooded areas of Montérégie, which public health monitors closely.
The local calendar
- April to June: carpenter ants; the start of tick season in the woods.
- June to September: wasps, and mosquitoes near the river and the lake.
- September to November: mice and Asian lady beetles.
- Winter: mice already inside, active in basements.

Frequently asked questions
Why so many carpenter ants in Châteauguay?
Many properties are wooded or border the Châteauguay River and Lac Saint-Louis. Dead wood, stumps, moisture and branches touching the roof: exactly what carpenter ants look for. They set up their main nest outdoors, then satellite nests in the house.
Are there ticks in Châteauguay?
Montérégie is one of the Quebec regions where public health closely monitors the black-legged tick. Wooded areas and tall grass, like those on Île Saint-Bernard, are its typical habitat. Clear vegetation around the yard and check yourself after time outdoors.
Does the wildlife refuge bring nuisance animals into homes?
A rich natural area mostly brings wildlife into nearby yards: skunks, raccoons, squirrels. Those animals are handled by exclusion (closing access under decks and into the attic), not by extermination.
Do mice get into homes near Highway 30 more often?
Newer neighbourhoods bordering open land are more exposed in the fall. But whether a house gets picked mostly depends on poorly sealed foundations and utility entries, whatever the neighbourhood.
